DNS perhaps?
I solved it first reading http://www.goldfisch.at/knowledge/70 : "If sendmail takes very long time for starting and output of mailq takes many seconds, than you might have a name-resolve-problem. Check logfiles for gethostbyaddr ... failed - entries and fix corresponding resolve-problem." which is what I did: % grep gethostbyaddr /var/log/maillog Feb 15 03:01:23 <myhostname> sendmail[71810]: gethostbyaddr(10.10.10.1) failed: 2 Feb 15 03:01:58 <myhostname> sendmail[71856]: gethostbyaddr(10.10.10.1) failed: 2 Feb 15 03:02:40 <myhostname> sendmail[72061]: gethostbyaddr(10.10.10.1) failed: 2 % I then found why I get this error, from http://www.sunhelp.org/faq/sendmail.html "QUESTION: Why does my Solaris machine generate the error "sendmail: gethostbyaddr failed" whenever I send mail? ANSWER: One of more of the IP addresses configured on your system does not have a matching entry in /etc/hosts. sendmail does a "reverse" lookup (input IP address, output hostname) when it starts up, generating the error. You can either fix /etc/host and your Nameservice, or ignore the message." Although I had an entry for the second ethernet port (10.10.10.1) in /etc/rc.conf, I didn't have it in /etc/hosts. I fixed /etc/hosts and all is fine now. many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 928 8233 Fax: +44 (0)117 929 4423 _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
